It has been observed that atmospheric aerosols can strengthen updrafts in deep convective clouds such as those that form in thunderstorms. Past work has linked such invigoration with the latent heat released by water condensation or freezing in chains of processes that depend on aerosol concentrations. Abbott and Cronin suggest a third possibility in which updrafts intensify because high aerosol concentrations increase environmental humidity by mixing more condensed water into the surrounding air, which in turn favors stronger updrafts. </p>
